To all whom it may" concern-,-

Be it known that I, KALMAN VON KANDQ, a subject of the Emperoref Austria and of the -Kingof Hungary; and-a resident of V ado Lig-ure, ini the-K'ingdom of Italy, have invented a new and usetul Improvement: in the, Suspension of- 'Li'quidI-Go'ntainers on Railway-Vehicles, 0t which the following is a specification,-

This invention relatesto an improvement in the-- suspensionof containers for liquid on railway vehicles,- and has-for its object toprovide an improved-construetion-by which the strains experienced; by the vehicle during its movement-- will not be communicated to=the walls of; the-container.-

When a largeand heavy container for liquidsis mounted directly upon the frame of the vehicle the walls i require to -be massive and- 1strongly braced-since the vehicle frame is 1 elastic" and; is subject to deformation due lac-running strains whenthevehr cleis service, and; such strains are communicated to the container. I walls and 1 give rise to heavy and dangerous stresses; The forces thus =-produced;: may be in some Y instances so great --tlrat it ispractically impossible to:--- make the container suflic'lently strong, within-the limits oh weight allowed, to withstand themw v It is L the. object of the present invention to: provide an improved 1 construction whereby-a container. can be suspended from the frame; such-1a manner; thflzt%d8f0131'fil2l tion of thevehiclewframepanl occur: without the container being. similarly -afi'ectedr g According to [my invention vI provide a frame in .whichthel container is 1 supported, this frame:being-suspendedfrom the vehicle it'rameirrsuch-1a manner-that; alterations in the :formof; 1311611317156]? *(lllBztQ: run.- ningstrains. can occur- 1 without. deforming the; container; :W alls:

F'lg,i 4:' is a side elevations partly sectionaL and Fig.

5' is aplan view; partly sectional showing a deta1l.' Fig-6 is an end elevation partly sectional of the part shown-in Fig, 4 and Fig; 7 is a section on the line VII- -VII' of F ig. 4.

Referring now to the drawings, a container indicated in broken and hatched outline at 1 is supportedin a frame-consisting of two pairs of parallel -members-2-, and 4:, 5 respectively; Theanembers '2 and 3 aresupported-by stirrups- 6 from-themembers 4;, -5, said stirrups consisting of-strap's bent to a rectangular form,tne upperparts of which surround the members-4E, 5,'the H lower parts being providedwith orifices 7 throughwhich the members 2, '8 are passed. This-construction will be clearly understood from Figs. 3 and 6 of the,drawings. The frame members 4, 5' are-provided with seats 8 which rest upon knife edges-9 which' are firmly secured between plates-10 0f substantially triangulartorm (see Fig. 4:) said platesbeing provided with knife edges 11 which in their turn are borne upon seats l2 secured in plates-13 Which-are "rivetedto stays or links 14, 15*, 16, these-latten being directly supported froml the side beams 17 of the ,car. The plates-10 011 'each sid'e *of the car arefurthen connected by'links 18 pivoted thereto as shown. It will'be readily seen that the plateslO in effectforn bell crank levers which are pivoted at 11, 12 to the vframe work 0f the vehicle and directly support; the frame: 2, '3, :4 and 5, through-theaknife edges 9. The stirrnpsfi are connected through links119 to bellr'crank levers-2O.,1 pivoted at 2l on the cross bearers 22 which form part of the framework of the vehicle, the othenendloisaid bell crank levers 20 being connected a link 23.

Itzwill be readily seen'fromithe-eonstruction hereinabove. described that thev'weight of: the container is, in the-first: instance,

frameand is transfer-red'lthrough the'stirrups 6 to the-cross members 4,15 and from the side-beams 17: of the vehicle;

borne byuthe lowermembers:2, 3 of the 'ment in a lateral:direction-. isprevented by 1 Any downward movemen-teot thief-ra ine member 4- at one end of the container will, through the plates 10 and connecting link 18, be transmitted to the corresponding plates 10 at the other end of the container and cause an upward movement of the frame member 5. Consequently the center of gravity of the container, which may be considered to lie in a plane midway between its ends, will neither be raised or lowered.

Owing to the flexible nature of the connection between the frame 2, 3, 4, 5, and the vehicle frame 17 any deformations of the latter will not result in strains being trans mitted to the side of the receptacle.

Furthermore, if one side of the receptacle is tilted owing to an upward movement of the frame 'member' 3, for example, this movement is transmitted through the stirrup 6, link 19, bell crank 20, link 23, and corresponding bell crank 20 and stirrup 6 at the other side of the vehicle, to the frame member 2 and causes the same to descend. Consequently in this case also the center of gravity which may be considered to 'be in a longitudinal plane approximately midway between the sides of the tank is also neither raised nor lowered. The construction therefore substantially prevents movement of the center of gravity of the tank when the vehicle is tilted either sidewise or in a longitudinal direction.

The construction can be further improved by providing additional links 24: connected at one end to the stirrups 6 and at their otherends to bell cranks 25 pivoted at 26 to the vehicle frame, the free ends of said hell cranks being connected by a link 27.

o It will be readily understood without further explanation that a lateral movement of one end of the container and frame in a horizontal plane will therebycause a corresponding movement of the other end of the container in an opposite direction and will in effect rotate the same around a vertical axis passing through its center of gravity. Consequently lateral movements due to centrifugal forces and other stresses under ordinary service conditions will be avoided. I claim as my invention:

1. In a vehicle, the combination .with a body portion, of a frame, levers pivotally connected to the frame, and means for pivotally supporting the body portion on said levers to permit the same to effect a movement of rotation relative to the frame while maintaining the center of gravity thereof substantially stationary.
